By way of non-limiting example, FIG. 2 illustrates base assembly 11, in accordance with one or more implementations. In some implementations, first mechanical coupling 16 may be a threaded coupling. In some implementations, first mechanical coupling 16 may be a female threaded coupling configured to fit together with second mechanical coupling 26 of container assembly 12 (in FIG. 1).
(17) In some implementations, base assembly 11 may have a cylindrical shape. In some implementations, the cylindrical shape of base assembly 11 may have a diameter between 2 and 4 inches. In some implementations, the cylindrical shape of base assembly 11 may have a diameter between 2.5 and 3 inches. Such a diameter may improve portability, as well as allow blender 100 to be stored in a cup holder, e.g., in a vehicle.
(18) Referring to FIG. 1, container assembly 12 may include one or more of a proximal end 21, a distal end 22, a container body 20, a second mechanical coupling 26, a filter 27, a cap 24, a coupling 24a, a carrying strap 3, and/or other components. Container body 20 may form a vessel to hold and/or contain foodstuffs within container assembly 12. In some implementations, the dimensions of container assembly 12 may be such that the internal volume of container assembly 12 can hold 10, 12, 14, 16, 18, 20, 22, or more ounces. In some implementations, container assembly 12 and/or container body 20 may have cylindrical shapes. In some implementations, the cylindrical shapes of container assembly 12 and/or container body 20 may have a diameter between 2 and 4 inches. In some implementations, the cylindrical shapes of container assembly 12 and/or container body 20 may have a diameter between 2.5 and 3 inches. In some implementations, container body 20 may be transparent. By way of non-limiting example, FIG. 3 illustrates container assembly 12, in accordance with one or more implementations. In some implementations, second mechanical coupling 26 may be a threaded coupling. In some implementations, second mechanical coupling 26 may be a male threaded coupling configured to fit together with first mechanical coupling 16 of base assembly 11 (in FIG. 1).
(19) Referring to FIG. 1, set of blades 13 may be rotatably mounted to base assembly 11 to blend foodstuffs. In some implementations, set of blades 13 may be disposed at or near proximal end 21 of container assembly 12 during blending by blender 100. In some implementations, set of blades 13 may include 1, 2, 3, 4, 5, 6, 7, 8, or more blades. In some implementations, as depicted in the upright configuration of blender 100 in FIG. 1, set of blades 13 may includes six blades. In some implementations, set of blades 13 may include at least two downward blades, which may prevent and/or reduce foodstuffs remaining unblended when disposed under the upward blades. In some implementations, set of blades 13 may include at least four upward blades. In some implementations, including six blades may be preferred over including less than six blades, in particular for blending ice and/or ice cubes. By using more blades, more points of contact will hit the ice at substantially the same time, which reduces the likelihood that a piece of ice is merely propelled rather than crushed and/or blended, in particular for implementations having limited power, such as disclosed herein. As used herein, directional terms such as upward, downward, left, right, and so forth are relative to FIG. 1 unless otherwise noted. In some implementations, set of blades may be configured to rotate around a longitudinal axis of blender 100.
(20) Electrical motor 14 may be configured to rotationally drive set of blades 13.
In some implementations, electrical motor 14 may operate at a voltage between 5V and 10V. In one or more preferential implementations, electrical motor 14 may operate at a voltage of about 7.4V. In some implementations, electrical motor 14 may be configured to spin set of blades 13 at a maximum speed between 20,000 rotations per minute (RPM) and 30,000 RPM. In one or more preferential implementations, electrical motor 14 may spin set of blades 13 at a maximum speed of about 22,000 RPM. Electrical motor may be configured to be powered by rechargeable battery 15. Simultaneously, in some
implementations, electrical motor 14 may be further configured to be powered through standardized charging interface 25, though that may not be the preferred way of operating blender 100. In one or more preferential implementations, no power is supplied to electrical motor 14 from an external power source during blending by blender 100. In some implementations, control circuit 17 may be configured to control electrical motor 14 during rotation of set of blades 13. For example, control circuit 17 may control the speed of the rotation of set of blades 13 during blending by blender 100.
(21) Rechargeable battery 15 may be configured to power electrical motor 14. In some implementations, rechargeable battery 15 may be configured to power electrical motor 14 such that, during blending by blender 100, no power is supplied to electrical motor 14 from an external power source. In some implementations, rechargeable battery 15 may be non-removable. As used herein, the term "non-removable" may mean not accessible to users during common usage of blender 100, including charging, blending, cleaning, and storing for later use. In some implementations, rechargeable battery 15 may have a capacity between 1000 mAh and 4000 mAh. In one or more preferential implementations, rechargeable battery 15 may have a capacity of about 2000 mAh. In some implementations, control circuit 17 may be configured to control charging of rechargeable battery 15. For example, control circuit 17 may control the transfer of electrical power through standardized charging interface 25 into rechargeable battery 15. For example, responsive to a detection that rechargeable battery 15 is fully charged, control circuit 17 may prevent the transfer of electrical power through standardized charging interface 25 into rechargeable battery 15.
(22) Standardized charging interface 25 may be configured to conduct electrical power to rechargeable battery 15. In some implementations, standardized charging interface 25 may be configured to conduct electrical power to charge rechargeable battery 15, e.g., from an external power source. In some implementations, standardized charging interface 25 may be configured to support wireless charging of rechargeable battery 15, e.g., from an external power source, including but not limited to induction-based charging.
In some implementations, standardized charging interface 25 may be a universal serial bus (USB) port configured to receive an electrical connector for charging rechargeable battery 15. In such a case, the electrical connector may be connected to an external power source. In some implementations, standardized charging interface 25 may be covered for protection and/or other reasons.
(23) First mechanical coupling 16 of base assembly 11 may be configured to couple base assemble 11 to container assembly 12. In some implementations, first mechanical coupling 16 may be a threaded coupling. In some implementations, first mechanical coupling 16 may have a parallel thread.
(24) Detector 18 may be configured to detect whether first mechanical coupling 16 of base assembly 11 is engaged with second mechanical coupling 26 of container assembly 12. In some implementations, detector 18 may be configured to detect whether first mechanical coupling 16 of base assembly 11 is engaged with second mechanical coupling 26 of container assembly 12 to couple base assembly 11 to container assembly 12. In some implementations, operation of detector 18 may use one or more magnetic elements. For example, in some implementations, one or more magnetic elements are included in container body 20 at or near proximal end 21 of container assembly 12.
Engagement may be detected responsive to these one or more magnetic elements being aligned and sufficiently close to one or more matching magnetic elements that may be included in base assembly 11 (e.g., at or near first mechanical coupling 16 of base assemble 11).
(25) Indicator 28 may be configured to illuminate in various colors (red, blue, etc.) and/or patterns (solid, fast blinking, slow blinking, alternating red and blue, etc.). Indicator 28 may convey information regarding the operational status of blender 100 to a user. The operation status of blender 100 may be determined by control circuitry 17. Indicator 28 may be controlled by control circuitry 17. For example, if indicator 28 is solid red, blender 100 may be charging and/or insufficiently charged to blend. For example, if indicator 28 is solid blue, blender 100 may be ready for blending. For example, if indicator 28 is alternating red and blue, blender 100 may not be ready for blending due to base assembly 11 and container assembly 12 not being coupled properly and/or fully. For example, in some implementations, threaded couplings between assembly 11 and container assembly 12 may need to be tightened sufficiently for proper blending, and indicator 28 may warn the user when the treaded couplings are not tightened sufficiently.
(26) Power button 29 may be part of the user interface of blender 100. Power button 29 may be configured to be engaged manually by the user, for example by pushing power button 29 to turn blender 100 on and off. In some implementations, control by a user of blender 100 may be based on a switch (not shown), a touchscreen (not shown), voice-controlled operation (not shown), gesture-based operation (not shown), and/or other types of user interfaces suitable to turn consumer appliances on and off.
(27) Control circuitry 17 may be configured to control different functions and/or operations of blender 100, including but limited to turning blender 100 on and off, charging of rechargeable battery 15, controlling of electrical motor 14 regarding and/or during rotation of set of blades 13, determining whether first mechanical coupling 16 is engaged with second mechanical coupling 26, controlling operation of indicator 28, and/or performing other functions for blender 100. In some implementations, control circuitry 17 may be configured to prevent rotation of set of blades 13 responsive to a determination that first mechanical coupling 16 of base assembly 11 is not engaged (or not engaged properly for the intended operation of blender 100) with second mechanical coupling 26 of container assembly 12. In some implementations, control circuitry 17 may be configured to control indicator 28 to convey information regarding the operational status of blender 100 to a user. For example, indicator 28 may include a light that can illuminate in various colors and/or patterns. In some implementations, control circuitry 17 may be implemented as a printed circuit board (PCB).
(28) Proximal end 21 of container assembly 12 may be disposed near set of blades 13 during blending of blender 100. Distal end 22 of container assembly 12 may be disposed opposite proximal end 21.
(29) Second mechanical coupling 26 of container assembly 12 may be disposed at or near proximal end 21 of container assembly 12. Second mechanical coupling 26 may be configured to engage first mechanical coupling 16 to couple base assembly 11 to container assembly 12. In some implementations, first mechanical coupling 16 and second mechanical coupling 26 may be threaded couplings. In some implementations, first mechanical coupling 16 and second mechanical coupling 26 may have parallel threads.
(30) Cap 24 may be disposed at or near distal end 22 of container assembly 12. In some implementations, cap 24 may be removable. For example, removing cap 24 may create an opening at distal end 22 of container assembly 12. In some implementations, blended foodstuffs may be removed through this opening, e.g., by pouring. By way of non limiting example, FIG. 5 illustrates a bottom-side up view of cap 24 (together with filter 27), in accordance with one or more implementations. In some implementations, cap 24 may include a threaded coupling 27b that is configured to engage with container body 20 (as shown in FIG. 1 and FIG. 4). In some implementations, the combination of cap 24 and filter 27 may include a threaded coupling 27b that is configured to engage with container body 20 (as shown in FIG. 1 and FIG. 4). In particular, in some implementations, threaded coupling 27b may be a male threaded coupling configured to fit together with threaded coupling 20a of container body 20 (shown in FIG. 4). In some implementations, once cap 24 and filter 27 have been removed from container body 20 and/or container assembly 12, an opening 20b is formed at the top of container body 20, through which foodstuffs may be removed from container body 20. In some implementations, cap 24 may include a spout, indentation, and/or other shape of its structure that may be used to pour and/or drink from. For example, such an opening may be coverable during blending of blender 100.
(31) Referring to FIG. 1, in some implementations, coupling 24a of container assembly 12 may be configured to removably couple cap 24 to container body 20 and/or other components of container assembly 12. In some implementations, coupling 24a of container assembly 12 may be configured to removably couple cap 24 to filter 27. In some implementations, coupling 24a may be a threaded coupling. In some implementations, coupling 24a may have a parallel thread.
(32) Filter 27 may be configured to strain blended foodstuffs, including but not limited to pulp and other suspensions. In some implementations, filter 27 may be removable. By way of non-limiting example, FIG. 6 illustrates how filter 27 and cap 24 may fit together for use with blender 100, in accordance with one or more implementations. Once filter 27 is turned over, threaded coupling 27a may fit together with threaded coupling 24a of cap 24. In some implementations, threaded coupling 27a may be a male threaded coupling, and threaded coupling 24a may be a female threaded coupling. In some implementations, filter 27 may be coupled to container body 20 without cap 24. By way of non-limiting example, FIG. 7 illustrates a combination of container body 20 and filter 27. By virtue of the holes in filter 27, a liquid within container body 20 may be strained through filter 27 (assuming that in such a scenario container body 20 is coupled to base assembly 11 (not shown).
(33) Referring to FIG. 1, carrying strap 3 may be configured to carry blender 100.
(34) Although the present technology has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred implementations, it is to be understood that such detail is solely for that purpose and that the technology is not limited to the disclosed implementations, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present technology contemplates that, to the extent possible, one or more features of any implementation can be combined with one or more features of any other implementation.
